Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

The pull of gravity on a plate that is being subducted

The transfer of heat by the mass movement of heated particles into an area of cooler fluid

The process when one tectonic plate moves underneath another

As the plate move apart magma comes up and cools make more floor

DIVERGENT LANDFORM (LAND)

DIVERGENT LANDFORM (SEA)

Is When Tectonic plates or fragments of the lithosphere move toward one another and collide.

CONTINENTAL V.S CONTINENTAL

CONTINENTAL V.S OCEAN

Caused by ocean vs ocean

Collision between two of the planet's tectonic plates and one plate goes under another

Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches.

Marianas Trench

San Andreas fault, earthquakes, no crust is destroyed or created and it slides horizontally
